Enraged by jealousy, Louis Vasquez followed his wife from their home in Orlando to Sanford Saturday and got arrested on domestic-violence charges.

Vasquez, 27, got out of jail Sunday. On Monday, he shot his wife to death, then turned the gun on himself the Volusia County Sheriff's Office said.

Vasquez and Linda Latoya Vasquez, 22 — formerly Linda Pearson — were newlyweds, having married just last July. But at the end of December, his relationship status already had gone from "married" to "it's complicated" on his Facebook page.

Suspecting that his wife was having affairs, he rented a U-Haul truck and followed her Saturday after they argued, a police report shows. He caught up with her in the median of State Road 46, where her car broke down.

Louis Vasquez punched his wife, dragged her by the arm, put her in a headlock and threatened to shoot her if she didn't get in the truck, Linda Vasquez told police. He also threatened to shoot a good Samaritan who had stopped with his girlfriend to help Linda Vasquez, the man told officers.

Officers confiscated a Smith & Wesson.38-caliber handgun they found in Vasquez's right back pocket. They also arrested him on charges of aggravated assault with a firearm, aggravated assault with a weapon/domestic violence and domestic-violence battery.

He was released from jail Sunday on $5,000 bail but ordered to stay away from his wife and their home.

But Vasquez caught up with Linda Vasquez Monday at his mother's house in DeBary. A neighbor saw Linda Vasquez run to her car, then saw Louis Vasquez run out of the house, ordering his wife to "Put the phone down. I said put the phone down," a sheriff's report states.

The neighbor saw Vasquez point a gun at his wife, shoot her once, then shoot her again after she fell, she told investigators. Louis Vasquez then shot himself, a sheriff's report states. He died a short time later at Halifax Health Medical Center in Daytona Beach. A deputy found a Glock Model 22, a .40-caliber semiautomatic handgun lying in the grass near the driveway.

"It's just a tragically sad situation," said Sherry Holt, Louis Vasquez's aunt, who lives in Georgia. "They were both young. I don't know what made him do that."

Louis Vasquez was an apprentice air-conditioning technician who had worked on the Amway Center and the Veterans Affairs Medical Center at Lake Nona, said Carl Gregory, apprenticeship coordinator for Plumbers & Pipefitters Local 803, which also represents heating and air-conditioning technicians.

Those who worked with him described him as a quiet man who kept to himself.

"I never heard him say a harsh word to anybody," said Fred Webster, labor manager for John J. Kirlin, the construction company that employed Vasquez. "He was a reliable sort of guy."

Vasquez's mother raised him in DeBary, and he studied his trade at Daytona Beach Community College — now Daytona State College, said his father, Alex Hernandez Vasquez, 57, of Orange County. Father and son were separated for much of Louis Vasquez's life, but the boy was never forgotten, Alex Vasquez said.
